Optical glass dome manufacturer to share with you: Optical glass is the foundation and important part of the optoelectronic technology industry. With the rapid advancement of optoelectronic technology, the application field of optical glass materials continues to expand, especially with photographic functions The popularization of smart terminals has promoted the development of the optical lens industry to a certain extent, and has become an important driving force for the development of the optical glass industry.

High-end environmental-friendly optical glass has high technology content and large added value. Its sales price can reach dozens of times of traditional optical glass. It is the main profit growth point of the optical glass industry at present. Future development direction.
Traditional ordinary optical glass, due to its low technical content and limited use functions, has gradually been replaced by lanthanide series and environmental-friendly special optical glass with higher technical content and wider use functions.
(1) Lanthanum optical glass
Rare earth optical glass in optical materials, also known as lanthanide optical glass, contains more rare earth lanthanum oxide in its composition, which has the characteristics of high refractive index and low dispersion. Its characteristics are that it can effectively expand the field of view of the lens, improve the imaging quality of the instrument, and make the lens compact and lightweight. It is currently used in digital cameras, digital cameras, scanners, LCD projectors, digital copiers, CD-ROMs and The high-end optical and electronic information materials widely used in DVDROM reading lenses have recently been used in camera optical systems for mobile phones, and their development prospects are considerable. With the rapid development of the optoelectronic information industry, it has gradually become the leading product of optical materials.
(2) Environmental protection series optical glass
Some countries in the world have successively promulgated and implemented environmental protection laws. If the use of lead oxide and arsenic oxide that are harmful to the human body is prohibited in glass, it is required to use environmentally friendly optical glass round windows in optical instruments and optoelectronic products. To meet this requirement, major manufacturers of optical glass in the world have developed a variety of environmentally friendly optical glass in recent years.
Among them, Japan's OHARA company has provided 31 varieties of lead-free and arsenic-free environmentally-friendly optical glass to the market since 1993. In 1996, the number of environmentally-friendly optical glass produced reached 93. The 111 types of optical glass are all free of lead and arsenic, and they are in the leading position in the world.
